We report on observations of the Be/X-ray binary system Swift J1626.6–5156 performed with Nuclear Spectroscopic Telescope ARray (NuSTAR) during a short outburst in 2021 March, following its detection by MAXI monitor and Spektrum–Roentgen–Gamma (SRG) observatory. Our analysis broadband X-ray spectrum source confirms presence two absorption-like features at energies E ∼ 9 17 keV. These had been p...

Abstract JWST’s Early Release Observations of the lensing cluster SMACS J0723.3–7327 have given an unprecedented spectroscopic look into high-redshift universe. These observations reveal five galaxies at z > 5. All detectable [O iii ] λ 4363 line emission, indicating that these high temperatures and low metallicities they are highly star-forming. In recent work, been studied using various te...
